thanks Chris.

You can get new genuine Husqvarna ex USA or Sweden, or an after market kit ex USA. Either will set you back around $500 with freight, depending on the exchange rate when you order. If your rod is ok (they can be), you can get a pin & bearing for around $100.

What do you need to check to determine if the rod is OK? Is it marking in the the bearing surfaces only or are there other issues?

Cheers

Been a long time since I've seen one bent or broken, so it really is just checking the bearing surfaces for undue wear, pitting, roundness, etc.
Cheers,

Hi All,

Thanks for the advice the rod is still in the bottom end and has no movement at all the  issue I have is when I turned over the  crank after taking the barrel off I notice fine bits of grit or sand coming up from the bottom end.

I washed it out about five times with petrol trying to get all the fine grit out but it still keeps  coming up from the bottom end, so I believe I will now have to split the cases, I was going to put new main bearings and seals in and I thought I would replace the rod when I had it apart but what will do now is check the rod and only replace if necessary.

Thanks for all your advice.

Huskys are notorious for corrosion of the cylinder studs falling into the crankcase when the cylinder is removed. A real pita and the cause of many a case splitting being necessary. Removing the cylinder with the engine upside down prevents this. A trap when working on a motor that hasn't been apart for a long time. You can seal the studs with silicon before installing the head to try and stop moisture getting into the studs. Good luck with the strip down.

I have the cylinders machined to take o'rings around the stud holes. Bit of a pain to do but saves a lot more pain down the track. If you've ever had a cylinder stuck from corrosion & crud, you'll understand completely.

could also be bits of big end from a "no oil in the fuel" run...they can produce a lot of fine metal "dust" especially seeing as its seized.
hopefully its stud gunk and corrosion seized..
